There are two places that are the usual ones to clear performance rights for motion pictures--The Motion Picture Licensing Corp. (www.mplc.com) and Movie Licensing USA (www.movlic.com).

For higher ed licenses, you could try Swank Pictures (www.swank.com)

For more info on these two organizations, see the UT copyright page at

If you have a lawful copy of the video, and you want to use it in the classroom for teaching purposes, why do you need public performance rights? In Canada, do you have an exception that allows for PP in the classroom without prior authorization? Just wondering.
